Classmates Video - Teaching Guide

Estimated time: 30-45 minutes Format: Follow along video with breaks to self assess. Solution revealed in video.

This is a hands-on coding project. Upon completion of the assignment, the student will have a working telephone application and a personal phone number that can be shared to provide connectivity with their friends/families/fellow classmates.

Prerequisites

Student should have a basic grasp of reading. The intended age range is 6-14 years. (All grownups are also very much welcome 💪)

Student will need an Internet connection and a web browser. We will be creating a free trial with Twilio. Using this free trial promo will double the amount of free credit you receive on signing up.

Previous programming experience is not required for the student nor the instructor.

Learning Objectives

After watching this video, the student will be able to:

  • Explain that coding can provide solutions to real world problems
  • Identify a tag and what characters make up the tag
  • Recall how to close a tag in a markup language
  • Identify common errors found in strict markup languages
  • Recall how to nest a tag in a markup language
  • Construct a telephone application that uses Text to Speech
  • Create a telephone application that connects caller's to a Conference call

Solutions

The video reveals the correct answers, but in case you want access to the various coding prompts:

8:35 - Say code (Make sure you have an open and closing tag, along with the proper casing!)

11:00 - Replace the initial saying with Connecting to classmates within the <Say> tag.

<Say>Connecting to Classmates</Say>

12:08 - Nest a <Conference> tag within the <Dial> tag.

<Dial><Conference></Conference></Dial>

Next we add the conference name.

<Dial><Conference>Classmates</Conference></Dial>

Final solution

Discussion Prompts

What other solutions can you think of that have been created to solve problems? How do they help?

Suggestion: Discuss Amazon.com and Grocery Store pickup for very relatable solutions they are seeing during the pandemic. Also consider Google Classroom / Seesaw. Discuss future feeling ideas: self driving cars/robots etc.

What made the coding parts challenging? How do you think you could get better at it?

Suggestion: If programming is new to them and probably has stricter rules than they will be accustomed to. Practice, practice, practice.

What do you want to build with code?

Suggestion: Anything is possible! Please share the responses with us! We are always looking for inspiration @craigsdennis
